nelly moser clematis - Knowledgebase Question

First year for the Nelly Moser Clematis - two vines were tied around a post. One vine produced two flowers and just dried up. The other is fine - so far. Do I cut down the one that dried? Or is it just dormant until next year? Next year does it bloom from the old, or send up new shoots from the ground? Thanks for the help!

Nellie Moser is Clematis montana, also known as Anemone Clematis. It's a vigorous grower, extremely hardy, and produces masses of 2-2 1/2" anemone-like flowers in early spring, opening white then turning pink. Your clematis flowers on old wood and can be pruned immediately after flowering to rejuvenate the plant or to reduce its size. When you prune, leave some main branches. New flowering shoots will develop from old wood, providing next spring's display of flowers. Cut back the dried up vine, it won't rejuvenate. However, new shoots should develop from the roots this summer to replace the lost one. Allow these new shoots to grow without pruning and next spring new flowering shoots should develop from it. Hope this clarifies things for you!
